Grown by us. Cut by us. Unmistakably DIAMONDBOI.
Rooted in Portuguese heritage and brought to life through our own diamond growing and cutting process, the Portuguese Cut Oval is a personal expression of our craft. We grow each lab diamond ourselves, then carefully cut it to reveal the intricate faceting and distinctive character that define this stone.
Its elongated silhouette draws the eye, while a captivating pattern of reflections invites a closer look. Every turn reveals another detail—a diamond you can keep discovering.
